SIM speed enhancement re-enabled and made configurable TI's original code supported SIM speed enhancement, but Openmoko had it disabled, and OM's disabling of speed enhancement somehow caused certain SIM cards to start working which didn't work before (OM's bug #666). Because our FC community is much smaller in year 2020 than OM's community was in their day, we are not able to find one of those #666-affected SIMs, thus the real issue they had encountered remains elusive. Thus our solution is to re-enable SIM speed enhancement and simply wait for if and when someone runs into a #666-affected SIM once again. We provide a SIM_allow_speed_enhancement global variable that allows SIM speed enhancement to be enabled or disabled per session, and an /etc/SIM_spenh file in FFS that allows it to enabled or disabled on a non-volatile basis. SIM speed enhancement is now enabled by default.

  PURPOSE : Decode elements of type nonCriticalExtensions

            An element of this type should never be encoded or decoded.
            If the coder faces an IE of this type, it should report a
            warning and continue decoding.
            Whenever a nonCriticalExtensions-IE is extended from NULL or 
            SEQUENCE {} to another type, its CCD coding type will change
            and the functions in this file will not be called for that IE
            any more.

            According to 3GPP TS25.331 V3.6.0, 10.1.1.1:
            Information elements applicable to choices reserved for future
            releases of the protocol shall be added to the end of the message.
            In future releases non critical informaion elements ... shall 
            be appended at the end of the message.
            See also 3GPP TS25.921 V4.3.0, 10.4.
